    Hello everyone,
    on a new debian 12 i used auto installer and it worked fine. I have a problem with point 5 regarding firewall configuration though. If I enter the ports as indicated, the server is no longer accessible in any way (ssh, http, ftp, etc). I have temporarily disabled UFW. How can I fix?
    Thanks in advance.

    So far as I am concerned you should just use the default without a need to manually set the firewall up as that is automated via default.

    I think to fix that you should undo your manual set up of firewalls and re-enable ufw which is set up there by default too.

    I do think that any firewall setup to be done manually is to your router, i.e. if you are behind NAT.
